Flattening the directory hierarchy for Plumpy

plumper.js

// Create a new directory called "Plumper" and dump all the files from "Plumpy" flat-ly into it
// Example: Plumpy/images/native/1.png -> Plumper/images_native_1.png
// Probably does not convert *all* but it does the most

// Packs from:
// https://github.com/acquitelol/rosiecord/tree/master/Packs/Plumpy

const fs = require("fs");
const path = require("path");

const origPath = path.join(__dirname, "Plumpy");
const dumpPath = path.join(__dirname, "Plumper");

try {
    // Remove the "dump" directory if it exists
    fs.rmSync(dumpPath, { recursive: true });
} finally {
    // Create a new "dump" directory
    fs.mkdirSync(dumpPath, { recursive: true });
}

const walk = (dir, callback) => {
    fs.readdirSync(dir).forEach(f => {
        const dirPath = path.join(dir, f);
        const isDirectory = fs.statSync(dirPath).isDirectory();
        isDirectory ? walk(dirPath, callback) : callback(path.join(dir, f));
    });

walk(origPath, filePath => {

    // Example: Plumpy/images/native/1.png -> Plumper/images_native_1.png
    const assetName = filePath
        .replace(origPath + "\\", "") // Remove the original directory path
        .replace(/\\/g, "_").replace(/\//g, "_") // Replace all \ and / with _
        .replace(/@[0-9]+x/, "") // Remove @[number]x from the file name
        .replace(/-/g, "") // Replace all '-' with nothing

    // Dump the file to the dump directory
